Hopper 1 installs on base 8 through outer barrel 7 down, and pivot 4 installs in outer barrel 7 through the pivot seat, and belt pulley 5 is located hopper 1 down and installs in 4 upper ends of pivot, and welt 6 installs at outer barrel 7 inner wall.
The hammer body comprises an upper hammer body 21, a middle hammer body 22 and a lower hammer body 23, and the upper hammer body 21, the middle hammer body 22 and the lower hammer body 23 are sequentially arranged on the rotating shaft 4 from top to bottom; the hammer comprises an upper hammer 31, a middle hammer 32 and a lower hammer 33, wherein the upper hammer 31, the middle hammer 32 and the lower hammer 33 are respectively arranged on the upper hammer body 21, the middle hammer body 22 and the lower hammer body 23.
The outer diameter of the upper hammer body 21 is smaller than that of the middle hammer body 22, the outer diameter of the middle hammer body 22 is smaller than that of the lower hammer body 23, so that the distance L1 between the upper hammer head 31 and the lining plate 6 is 30-100mm, the distance L2 between the middle hammer head 32 and the lining plate 6 is 20-80mm, and the distance L3 between the lower hammer head 33 and the lining plate 6 is 10-60 mm.
Example 2:
the novel structure of the crushing sand making machine comprises an upper hammer body 21, a middle hammer body 22 and a lower hammer body 23 which have the same outer diameter, wherein an upper layer lining plate 6 is directly arranged on an outer cylinder body 7, a thin backing plate 9 is additionally arranged on the back surface of the middle layer lining plate 6 and then is arranged on the outer cylinder body 7, a thick backing plate 10 is additionally arranged on the back surface of a lower layer lining plate 6 and then is arranged on the outer cylinder body 7 so as to ensure that the distance L1 between an upper hammer head 31 and the lining plate 6 is 30-100mm, the distance L2 between the middle hammer head 32 and the lining plate 6 is 20-80mm, and the distance L3 between a lower hammer head 33 and the. The rest of the structure is the same as in example 1.
The process of crushing and making the sand is to crush large materials into medium materials, crush the medium materials again and finally become the process of the sand materials meeting the requirements. The material passing through the upper hammer head is large and uneven in particle size, a large space is needed for the material to enter a gap between the hammer head and the lining plate, and the particles become small through primary extrusion and shearing; only by adjusting the gap between the hammer head and the lining plate, the minimized material can be subjected to the maximum extrusion force and the maximum shearing force, so that the ineffective friction loss is reduced, and the particles become smaller through the second-stage extrusion and shearing; and the third stage is adjusted to ensure that the clearance between the hammer head and the lining plate is smaller, and the proportion of qualified sand grains reaches the highest through the effective extrusion and shearing of the third stage. Therefore, gaps between the lining plate and the hammers are designed according to the size of the materials, and the gaps between the hammers and the lining plate are reduced from large to small, so that the materials with different sizes are subjected to the same large extrusion force and shearing force in a proper space, and the crushing efficiency is improved.
